The invention relates to a system and method of testing flexible direct-current transmission valve control equipment. The system comprises a flexible direct-current valve control system, an RT-LAB real-time simulation platform and an RT-LAB interface case. The flexible direct-current valve control system comprises a converter valve control unit and control units of six bridge arms which are in control connection with the converter valve control unit. The control unit of each bridge arm is further connected with a corresponding bridge arm sub-module interface unit. One of the bridge arms is used as a sub-module test bridge arm, and a sub-module interface unit of the sub-module test bridge arm is connected with the RT-LAB real-time simulation platform through the RT-LAB interface case. The control units of other five of the bridge arms are all connected with the RT-LAB real-time simulation platform through the RT-LAB interface case. Through the application of the system and method, each function of the valve control equipment can be completely tested, and the problem that amount of system wiring is too high as each sub-module is independently connected is solved.
